BURNER.

Speciflcation of .Letters Patent. Patented DIar. 5, 1912. application med september 23, 1909. serial Ne.' 519,200.

.To all whom it may concern:

`Be it known .that I, WILLIAM BOOTH, a cit-izenvof the United States, 'residing at Scranton, .in the county of Lackawanna and State of Pennsylvania, have invented cer-v tain new and useful Improvements in Burn-l ers; and I do hereby declare the following fuel passing through the burner as it leaves the burner into the combustion chamber.

With these and other objects inview, the

invention comprises eertain novel construeprises a' housing havin lchute 14 is cont-rolle tions, 'combinations and arrangements of parts as will be hereinafter `fullyv described and claimed.

In the drawings z-Figure 1 is a View in vertical, longitudinal section of the improved burner. Fig. 2 is a longitudinal horizontal section taken on line 2-2 of Fig. 1. 4

Like characters of reference designate corresponding parts throughout Ithe several views. f

lIn general form'the burner which forms the subject-matter of this application comits sides as 10 at the feed end substantial y or approximately parallel but preferably diverging as .the Walls 11 between'the coal feed and the discharge end.:l The bottom 12 of the housing and l@insito 13 of the burner; are preferably substantial y parallelfwith a pipe or chute 14'openin into the topfor the introduction of coal. he feedin of coal through the by a slide valve l5 having an opening 16 to permit the coal to pass through and be controlled in any approved manner as by the lever 17 pivoted as at 18. Instead of entering the housing at right angles the chute 14 is provided with a 'rounded corner or side,19 to prevent to a great extent the clogging of the coal introduced. To movethe coal discharged through the chute 14 longitudinally t rough the housing a steam jet is provided as at 20 having-a slit lor discharge orifice 21 extendlng'substantially the entire Width of the housing, such steam jet 'being preferably 4fan-shaped in top p lan Vand convergingI toward the front end in vertical section as shown at Fig. 1. Steam is admittedto the nozzle 20 through a pipe 22. and as coal is dropped through the chute 14 it elicouulters the jet of steam from the orifice 21 and ters a blast of steam or air from the orifices 24 whjclrspreads the coal laterally upon"the fuel surface in the combustion chamber.

To lit the liurner for burning oil withthe coal as above described an opening 25 is pro- .vided adapted to be connected with the source of oil supply which'will drip orA run down upon the to of the steam nozzle 20 and by reason-of tiie inclined position o its top surface will run over the lower edge and drip down in front'of the steam jetissuing from the orifice 21 and be. atomized to burn alone or to mi); with the coal being introduced through the chute 14. An opening 26' is `also provided for connecting with the source of .compressed air which may be added to the jet of steam issuing from the e orifice 21 to force the coal through the housing or may be employed only incase'of clogging of the burner or'maybe employed wholly in lieu of steam issuing from the nozzle 20. l

i It will thus be seen that the burner constructed as shown is adapted for use with -both coal and oil such fuel to be -fed into the combustion chamber either by steam or air or both steam and air.

While the nozzle 20 has been described as a steam nozzle it Awill be apparent that it may be employed equallyas well with compressed air in places where steam supply would not be'readily available.

By the construction of the inlet chute 14.-y y

with the rounded cerner 19 the burner is capableyof taking care of coal 1n various conditions ra'ngmg from a powder to coal `thermore when the spreader is used with steam as the spreading agent the advantages of mixing steam with a fuel is attained.

What I claims is:-

' y. In a burner, a housing, means to introducem solid fuel upon the floor of the housing,` a nozzle extending transi-*ersely across the housing and having an inclined upper sur-- face, such nozzle being adapted to direct a current of fluid under pressure against the fuel upon the flooring of the housing, means to introduce liquid fuel upon the inclined upper surface of the nozzle, and vmeans at the discharge end of the housing adapted to i spread the fuel as discharged.

ln testimony whereof I aiiix my signature in presence of two Witnesses.
